角度选择：所选值不会立即显示

Question

I'm using angular-chosen in my angular application. I have in a modal, different inputs and a select chosen . The modal let the user add or edit person's informations. My problem is that in the edit mode, the selected value of the chosen is not displayed at the first time. It's just when I reopen the modal that I can see the selected value. I verified if the data takes too much time to be loaded, but it seems like it's a problem with the chosen and the modal. This is how I display it:

 <select id="school" name="school" 
   no-results-text="'No data'" chosen
     disable-search-threshold="1" ng-model="person.school"
     ng-options="school as school.name + ' - ' + school.districtName + ' - ' + school.regionName  + ' - ' + school.cityName  for school in schools track by school.id">
          <option value="">&nbsp;</option>
   </select>

您必须从控制器启动它，因为ng-model是未定义的 ，没有''或您要选择person.school = ''或者可能是在ng-init="person.school = ''"中选择的标签
